What is a Relational Database Management System (RDBMS)?
Core Definition
Data organized into tables (relations) with rows (tuples) and columns (attributes), governed by domains.
Key Concepts
  • Relations
  • Attributes
  • Tuples
  • Domains
Benefits & Examples
Ensures data integrity, consistency, and easy accessibility. Popular RDBMS include MySQL (62% market), PostgreSQL (14%), and Oracle (12%).
Entity-Relationship (ER) Modeling
Model Components
  • Entities represent real-world objects
  • Attributes describe properties
  • Relationships link entities
Advanced Concepts
  • Cardinality: One-to-one, one-to-many, many-to-many
  • Specialization & Generalization
  • Aggregation for complex relationships
Practical Example
University database modeling students, courses, and instructors using ER diagrams to represent associations and constraints.
Relational Algebra: The Theoretical Foundation
1
Fundamental Operations
Selection, projection, union, intersection, and difference form the query base.
2
Joins and Division
Include theta join, natural join, outer join, and division for complex queries.
3
Expressive Power
Enables formulation of precise queries and manipulation of relational data.
SQL: The Language of RDBMS
Core Commands
  • SELECT, FROM, WHERE
  • GROUP BY, HAVING, ORDER BY
DDL & DML
  • CREATE, ALTER, DROP
  • INSERT, UPDATE, DELETE
Advanced Features
  • Joins, Subqueries, Views
  • Indexes, Transactions
  • Security: 65% of breaches involve SQL injection
Schema Refinement and Normalization
1
1
Functional Dependencies
Understanding trivial, non-trivial, and full dependencies essential for schema design.
2
2
Normal Forms
Progressing through 1NF, 2NF, 3NF to BCNF to ensure data integrity.
3
3
Decomposition Benefits
Lossless-join and dependency-preserving ensure minimal redundancy and effective data structure.
4
4
Practical Normalization
Example: Converting a schema from 1NF to BCNF to eliminate anomalies.
Transaction Management and Concurrency Control
1
ACID Principles
Atomicity, Consistency, Isolation, Durability ensure reliable transactions.
2
Concurrency Control
Techniques like locking, timestamping, and optimism prevent conflicts.
3
Isolation Levels
  • Read uncommitted
  • Read committed
  • Repeatable read
  • Serializable
4
Recovery & Deadlocks
Logging, checkpointing for recovery; detection and prevention of deadlocks.
